Boris Hagelin of Sweden developed a long line of cipher systems, beginning with the B-21, B-211, C-35, C-36, C-38 (which later became America's M-209). The C-38 was then produced with a keyboard and motor in order to increase speed of operation.  A keyboard version of the C38 was produced and it was called the BC-38.  A later, minor update, resulted in the BC-543.

The machine is cased although the lid is not shown in the photo.
